The reverse side features a sliding grid used to solve wind-related problems. Wind Correction Angle (WCA)
The distance from the departure airport to the first waypoint is nautical miles (NM).
Read the corresponding time on the inner scale directly beneath 142, which aligns with 74 minutes. Exercise 1.2: Determining Groundspeed e6b flight computer exercises verified
True Course (TC): 198° | TAS: 130 kts | Wind: 260° at 20 kts. Step-by-step: Place wind direction (260) under true index. Mark wind speed (20 kts) up from the center (grommet). Rotate TC (198) under true index. Slide card so mark is on TAS (130).
Uses a sliding grid and a rotating azimuth plate to calculate the effects of wind on your heading and groundspeed. Category 1: Time, Speed, and Distance (Calculator Side) The foundational formula for the calculator side is: The reverse side features a sliding grid used
Locate the top-right cutout window labeled
The back side uses a sliding card and a rotating azimuth to solve wind vector problems. Exercise 1
Disclaimer: These exercises are for training purposes. Always verify flight planning calculations with current WX briefings and navigation logs. If you'd like, I can:
: Once set, the outer scale represents distance and the inner scale represents time. For example, if your speed is 120 knots, placing the rate arrow at 12 on the outer scale allows you to see that 26 nautical miles will take exactly 13 minutes. Decimal Management
: Use the wind slide to calculate the Wind Correction Angle (WCA).
